Perry's Index to the Aesopica
Fables exist in many versions; here is one version in English:
AESOP AND THE SOOTHSAYERS
People consider someone with real life experience to be more
reliable than a soothsayer, but they cannot say why: my little
fable will be the first to provide an explanation.
There was a farmer who had a flock of sheep, and those sheep gave birth to lambs
with human heads. Alarmed by this omen the farmer hurried off, deeply upset,
to consult the soothsayers. One soothsayer told him that the birth of lambs with
human heads indicated a matter of life and death for him as the 'head' of the
household, and a sacrifice would be required to ward off the danger. Another
soothsayer insisted that this was instead a sign that the man's wife had been
unfaithful to him, and that she had passed off other men's sons as his own; this
evil omen could only be averted by an even greater sacrifice. To make a long
story short, the soothsayers argued about their interpretations with one another,
heightening the man's anxiety with more and more causes for alarm. Aesop also
happened to be there, that old man who was nobody's fool: there was no way that
nature could play tricks on him! 'If you want to expiate this omen,' said Aesop,
'I suggest you supply your shepherds with wives!'
